The attachment of Glass Fiber Reinforced Concrete (GFRC) materials to building surfaces is critical for their stability and safety, with anchorage elements playing a vital role. In this study, researchers examined the corrosion of anchor elements in GFRC building facades to evaluate the effectiveness of a zinc-rich coating to prevent corrosion. The study investigated the corrosion formation of samples with and without a paint containing more than 85% Zn, applied as a coating with a 200 µm in the weld region. The researchers subjected embedded galvanized anchor elements coated 30x30x3 mm GFRC to a salt spray test according to ASTM B 117 standards. The corrosion in the weld regions of anchor elements with dimensions of 30x30x3 mm was investigated according to the same standard. The study results show that the corrosion test did not affect GFRC anchor elements according to the ASTM B 117 standard. The zinc-rich coating effectively prevented weld zone corrosion in GFRC facade anchorage elements. These findings contribute to the ongoing efforts to enhance the durability and performance of GFRC materials, which have been widely used in building facades for decorative and insulation purposes for many years.
In conclusion, the use of a zinc-rich coating is a reliable way to prevent weld zone corrosion in GFRC facade anchorage elements, ensuring their safe use and long-term service life. With the increasing demand for sustainable building materials, this study provides valuable information for designers, builders, and manufacturers to optimize the use of GFRC materials in building facades.
